Coxiella burnetii Phagocytosis Is Regulated by GTPases of the Rho Family and the RhoA Effectors mDia1 and ROCK [PDF]
The GTPases belonging to the Rho family control the actin cytoskeleton rearrangements needed for particle internalization during phagocytosis. ROCK and mDia1 are downstream effectors of RhoA, a GTPase involved in that process.

On the role of residue phosphorylation in 14-3-3 partners: AANAT as a case study [PDF]
Twenty years ago, a novel concept in protein structural biology was discovered: the intrinsically disordered regions (IDRs). These regions remain largely unstructured under native conditions and the more are studied, more properties are attributed to ...

The rab3A-22A chimera prevents sperm exocytosis by stabilizing open fusion pores [PDF]
At the final stage of exocytotis, a fusion pore opens between the plasma and a secretory vesicle membranes; typically, when the pore dilates the vesicle releases its cargo.

The late endocytic Rab39a GTPase regulates the interaction between multivesicular bodies and chlamydial inclusions. [PDF]
Given their obligate intracellular lifestyle, Chlamydia trachomatis ensure their access to multiple host sources of essential lipids by interfering vesicular transport.

Epac, Rap and Rab3 act in concert to mobilize calcium from sperm's acrosome during exocytosis [PDF]
BACKGROUND: Exocytosis of sperm's single secretory granule or acrosome (acrosome reaction, AR) is a highly regulated event essential for fertilization. The AR begins with an influx of calcium from the extracellular milieu and continues with the synthesis

Changes in renal WT-1 expression preceding hypertension development [PDF]
Background: Hypertension is a public health problem with mostly unknown causes, and where strong hereditary genetic alterations have not been fully elucidated. However, the use of experimental models has provided valuable information.

Controllability of protein-protein interaction phosphorylation-based networks: Participation of the hub 14-3-3 protein family [PDF]
Posttranslational regulation of protein function is an ubiquitous mechanism in eukaryotic cells. Here, we analyzed biological properties of nodes and edges of a human protein-protein interaction phosphorylation-based network, especially of those nodes ...
